Products High Performance Adhesive with Shock Absorbing Technology Du Pu Flex

Du Pu Flex

High Performance PU basic Flexible Adhesive.

Professional, superior-technology, two-part polyurethane system with high elasticity and no slip, suitable for high-resistance laying on flooring and wall of homogeneous and ceramic tiles, glass mosaic, large-size tiles, humidity sensitive marble and natural stone, on deformable and also non-absorbent substrates, wood and derivatives.

The Du Pu Flex technology ensures superior- performance adhesion for laying ceramic tiles and natural stone on porous surfaces such glass or metal. Du Pu Flex provides balanced thixotropy and superior-performance elasticity ensured by the use of stabilized polyurethane resins and micronised, pure mineral fillers, for rapid and secure laying operations on high deformable and high-expansion substrates.


  • Thixotropic adhesive specially designed for requiring high elasticity, adhesion and for stability with thermal shock with UV resistance.
